Abstract
A graphics application for simulating natural media drawing and painting may model a tablet stylus as if it were a virtual airbrush tool that sprays paint on a virtual canvas (tablet). The application may compute a conical shape of the paint spray, a target area in which to create an airbrush mark, and a target distribution of the paint to be deposited within the target area based on values of configurable parameters of the application and on 6DOF data collected from the tablet stylus and the tablet. The target distribution shape may be based on a hardness parameter. The virtual airbrush tool may create the mark using texture projection or by emitting multiple individual paint particles, which may have random sizes and velocity directions. In a hybrid mode, a granularity parameter may control the relative contributions of texture projection and particle emission in creating a given airbrush mark.
